Abstract Mining is vital for human sustenance and a crucial sector in the state economy. However, its impacts on the environment and biodiversity cannot be underestimated. Which are potent to the attract government’s attention. Environment and wildlife are subject to the harmful impacts of mining and its related activities. In this study, districts, namely Mardan and Mohmand have been targeted with respect to mining impacts. The assessment was carried out on wildlife adversely affected by the mining sector. The fauna has been keenly observed to bring the calculated risks and threat perception of the regional wildlife. Total 9 species of mammals, 21 species of birds, were recorded in District Mardan. While in District Mohmand 2 species of mammals, 9 species of birds, and 4 species of reptiles were studied. The Study explored that mining primarily responsible for land degradation. Which lead to food and agriculture losses. Several other factors like blasting, pollution, hunting, deforestation, habitat loss was also observed. Deforestation surfaced one of the major causes for extinction of fauna in the said region. preemptive measures are needed to seize the man-made catastrophe.

The subject. This article discusses the taxation of copper and nickel extraction in Australia, Canada, Chile, Kazakhstan and USAThe purpose of the article is to confirm or disprove the hypothesis that the experience of taxation of copper and nickel extraction in Australia, Canada, Chile, Kazakhstan and USA may be used for modifying the mineral extraction tax (MET) in Russia in order to increase the share of resource rent collected by the government.The methodology of research includes legal interpretation and economic analysis of the tax legislation in United States, Canada, Australia, Chile and Kazakhstan as countries with a well-developed tax system and a significant size of the mining sector in overall GDP.The authors select the legislative acts of these countries and regions that determine the procedure for collecting taxes in the extraction of metal ores, including those containing copper and nickel, as well as in the production of copper and nickel. The selected legislative acts are analyzed to determine the essential parameters of taxation. Particular attention is paid to the method of calculating the tax base, taking into account the approach to assessing the value of the taxable object, permissible tax deductions and exceptions, which allows authors to test the hypothesis put forward by determining which part of the value of a mineral resource is withdrawn during taxation.The main results, scope of application. Mineral extraction tax is the main tool for collecting natural resource rent in Russia. However, the level of taxation of solid minerals and coal is disproportionately low compared to their share in the production and export of raw materials. Thus, in 2018, the amount of MET on all minerals totaled 100.5 billion rubles, while the MET collected from oil and natural gas amounted to 5,979.6 billion rubles, i.e. 60 times as much. At the same time, the role of solid minerals in the Russian economy is comparable to the role of oil and gas. The share of the main types of minerals in the exports of the Russian Federation in 2018 was 20.4% compared to 56% for oil and gas, i.e. the difference of less than three times. The contribution of the industries related to the extraction of minerals and production of metals (mining of coal, ores, diamonds, metallurgy, fertilizer production) to the Russian GDP is about half as much as that of industries involved in the extraction and processing of oil and natural gas (7% and 14% of GDP respectively).In view of the above, it is important to develop a new approach to the taxation of solid minerals in Russia based on the world’s best practices. In order to identify the general principles of their taxation, we have conducted a detailed analysis of the tax legislation in a number of countries with a well-developed tax system and a significant size of the mining sector (the United States, Canada, Australia, Chile and Kazakhstan). We focused on the taxation of copper and nickel ores mining.Conclusions. The analysis of the international experience of taxation of copper and nickel mining sector reveals the following trend: the tax is calculated based on the market value of the extracted minerals, which is linked to the price quotes for the relevant product on an organized metal exchange (for example, the price of pure metal on the London Metal Exchange). This approach can be used in the Russian tax practice in several ways. First, Russia can adopt the Australian model where royalty on a mineral resource can be levied at the time of sale of the useful component irrespective of the processing stage (ore, concentrate or metal). The second potential model is based on the actual sale price of the product (provided it is sold in an arm’s length transaction) after deducting the costs of processing (i.e., smelting, enrichment etc., depending on the stage of processing) to arrive at the market value of the ore at the "mine mouth". The third is the Canadian model which is similar to the second one, but with the extraction costs also deducted from the sale price.

The purpose of this study is to examine the effect of fundamental factors on stock prices and to examine differences in the effects of fundamental factors on stock prices during the period of changes in mineral export policies. Fundamental factors are proxied by earning per share (EPS), net profit margin (NPM), return on equity (ROE), return on assets (ROA), and debt to equity ratio (DER). The research object is all companies in the mining sector listed on the Indonesia Stock Exchange (IDX) during the period 2014 – 2019, with a total population of 269 observations. The sampling technique was purposive sampling, with the results of 176 observations. The observation data came from 37 companies. Methods of data analysis using multiple regression and paired t-test. The results showed that only the EPS variable did not affect stock prices. Then, the study results also show that there is no difference in the influence of fundamental factors on stock prices during the export ban period and the reopening of the raw mineral export ban. This condition illustrates that investors still have confidence in the fundamental factors reported by companies in the mining sector.

Stock price fluctuations are natural and almost occur in all companies in various sectors, including companies in the oil mining sector so that price changes affect the company's financial performance and stock prices which can be analyzed fundamentally using financial ratios to aspects in the financial statements. The framework of this research is to analyze the effect of financial ratios on stock prices. The population and sample used are oil mining sector companies listed on the Indonesia Stock Exchange 2014-2018. The sampling method used is purposive sampling or judgmental sampling. Sources of data used are secondary data in the form of financial statements. The tool used for data collection is through the method of observation and analysis of the company's financial statements. The results showed, based on the t test value, stock prices were positively influenced by Return on Equity (ROE), Book Value (BV) and Price to Book Value (PBV), while negatively influenced by Debt To Equity Ratio (DER) and Net Profit. Margins (NPM). Based on the F test value, stock prices are positively influenced by ROE, DER, NPM, Earnings Per Share (EPS), BV, and PBV. Based on the coefficient of determination test (R2), stock prices are strongly influenced by ROE, DER, NPM, BV, and PBV by 91.5% and influenced by other variables by 8.5%.

Stope design is a core discipline within mining engineering. This study analyzes the current state-of-the-art of stope design through a survey addressed to mining industry professionals. In stope design research the dominance of empirical methods has slowly shifted towards numerical methods. Recent advancements have mostly focused on the development of stope optimization algorithms. The survey consisted of 19 questions and was distributed to stope design experts via email, LinkedIn messages, and the Mining Industry Professionals network forum. In total, 36 responses of satisfying quality from 20 countries were received and analyzed. No dominance of a single stope design method was recognized. Empirical methods and personal expertise are still used widely. However, a readiness for change in stope design practice was indicated in 87% of responses. The current needs of the stoping-based underground mining sector are to increase the amount of geotechnical data, automate stope design and implement related software, and integrate these into general mine planning. According to 70% of the participants, acquired geotechnical data should be available within three days to be employed in design practice. The industry is ready to implement more efficient stope design methods if they offer results proven in case studies.
